Severity: Normal Title: Net-SNMP: fixproc insecure temporary file creation Date: May 23, 2005 Bugs: #91792 ID: 200505-18

Synopsis ========
Net-SNMP creates temporary files in an insecure manner, possibly allowing the execution of arbitrary code.
Background ==========
Net-SNMP is a suite of applications used to implement the Simple Network Management Protocol.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/net-snmp < 5.2.1-r1 >= 5.2.1-r1
Description ===========
The fixproc application of Net-SNMP creates temporary files with predictable filenames.
Impact ======
A malicious local attacker could exploit a race condition to change the content of the temporary files before they are executed by fixproc, possibly leading to the execution of arbitrary code. A local attacker could also create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When fixproc is executed, this would result in the file being overwritten.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Net-SNMP users should upgrade to the latest available version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.2.1-r1"
Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
